Contact Kos Manager — support for boarding house owners.

We know running a kos is work that never really stops. When something goes wrong in the app, the sooner we know the details, the sooner it gets fixed. That is why every Kos Manager question goes to a single channel: support email. No queue numbers, no long forms — just tell us what is going on and we will follow up.

Official Kos Manager channels

These are the only official Kos Manager channels. If you come across another account, website, or phone number claiming to be Kos Manager, please do not share your account details or proof of payment with them.

• Support email: support@kosmanager.id for all help, subscription, and privacy matters.
• Instagram: @kosmanager.id for feature updates and kos management tips.
• TikTok: @kos.manager for short videos on how to use the app.
• Developer website: mdsolusindo.com, the official site of the developer behind Kos Manager.

What you can ask about

Most of the messages we receive fall into a few topics. If your question is one of them, our support team already has answers and clear next steps ready.

Using the features

How to add properties and rooms, move tenants between rooms, set due dates, create recurring bills, record partial payments, log electricity or water meter readings, and export reports to PDF and Excel.

Subscriptions and payments

Questions about the Starter and Professional plans, switching between plans, subscription periods, automatic renewal, or invoices for your kos business bookkeeping.

Account and data

Trouble signing in, changing your account email, moving your kos data to a new device, adding an admin to help with daily operations, or requesting deletion of your account and its data.

Bug reports and feature requests

If something on screen looks wrong, a report shows numbers that do not add up, or there is a feature you need that does not exist yet, let us know. Many Kos Manager updates started as feedback from owners who use the app every day.

How quickly do we reply?

Emails received on business days, Monday through Friday, are usually answered within one business day. Messages that arrive on weekends or national holidays are handled on the next business day. For issues that need a deeper look at your data — for example a mismatch in a monthly report — we usually share a progress update first and follow up with the solution.

Requests related to privacy and account deletion are processed under the terms of our Privacy Policy. You can also submit them directly through the Delete Account page.

Details that speed things up

To save us going back and forth with questions, include the following in your first email:

1. The email address you use to sign in to the Kos Manager app.
2. The device and operating system you are using, for example an iPhone on iOS 18 or Android 14.
3. The name of the kos property and room affected, if the issue involves specific data.
4. The steps you took before the problem appeared — a short note is enough.
5. A screenshot of what you see. One screenshot often explains more than a paragraph.
